Worked on the ecmwf/anemoi-datasets repository over a two-month period, focusing on stabilizing and enhancing data workflows through targeted bug fixes. Addressed template substitution issues by expanding regular expression support to handle hyphenated variable names, improving the robustness of template rendering and reducing errors in automated pipelines. Further improvements included resolving failures in forcings generation from xarray-zarr templates and correcting dimension ordering in xarray grid creation, ensuring accurate meshgrid outputs and reliable model inputs. All changes were implemented in Python, leveraging skills in data handling, NumPy, regular expressions, and Xarray to strengthen data integrity and reproducibility across workflows.
